What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[j91z28d1]

I grew up in Tampa and lived in Brandon/Riverview area during my 20-30s. You are right, it has grown dramatically cuz I do remember when it was god's waiting room with old people galore. The villages took a page from Sun City and expanded upon it....Wimauma used to be a place where migrant farm workers stayed due to the out of the way farms but a lot has changed in the past couple decades....Savor the time with your family and safe travels home!!

ha.. I was born and raised and Tampa, miss it a lot. left when I was about 35 for work.

haven't been back in years, my friends that are still down there tell me the place and pretty much all of FL is so over crowded these days I wouldn't even recognize it. they all want to move north to the mountains. done with it all.


I was thinking when I read Wimauma, it was all migrant workers following the crops. when we were kids a buddy of mine's aunt owned a small trailer park down there, he'd go down and help her clean it up from time to time. sure wasn't much there back then. Judy a place known because of a funny name.

Finally got around to adding an airtag in the 2500; working on some other measures to ensure it doesn't go anywhere but if it does at least this will let me find it.

Too bad OnStar didn't supply a 3G to LTE/5G module for the older cars, would have certainly upgraded.

It's up in the dome lights for anyone wondering; I wanted to ensure it was high enough that phones in the vicinity could contact it and also make it difficult for someone to find.

I read somewhere Canada made gm update the 3g in their cars but our govt didn't care haha.

if that was the case there would be some 4g modules floating around on ebay, etc..
you would think anyway

so I guess this scanner company has been sending all these car youtubers free scanners to show off on their videos.. well one I watch got me. little topdon Bluetooth dongle, 64$ on Amazon after 20$ off and taxes. thought eh, easy return and I've really wish I had something eazy on my phone that read shock pressure, tranny line pressure and stuff on that level. can't find the pids for torque app even thou I do use that often for the hybrid battery stuff but nothing 2 way and super slow updates of live data. this actually updates pretty quickly.

got a chance to play with it today, and gotta say. I'm impressed. full bi-drectional control of every module in the truck. brake bleed, turn run the air pump and all the crazy stuff too for the hybrid like inverter and steering rack Temps that almost nothing but the tech 2 has. current tranny ratio and motor Temp also since it's kinda a cvt. seems to do everything my tech 2 does in a cell phone app. even pulled up related tsb that look pretty current.

I got nothing.. but definitely keeping it around at this point

this tsb was all I could find on Canada upgrade from 2g to 4g for 2010 - 15 stuff. I just skimmed it cause 41 page pdf on my phone is a hassle to read lol

edit* file. to big, ugh.

Interesting. Can it read and reset trans fluid life and also program key fobs?

I'll look tomorrow, I didn't know tranny fluid life was a thing. I've changed mine and didn't know to reset anything.

key fob I don't know. I'll look, only thing I've done that on is my c6 and it was all done without a scanner. Just walk thru and place it in a certain spot in the glove box.

 

[j91z28d1]

I haven't got to check anything on my car but I walked into work to a Ford transit that had puked it's over flow bottle dry over night, so I tried it. it did pull up the code for a cylinder head temp sensor and had the snap shot data saved when it set.

pretty handy. I've got the dealer level Ford aurff at work but I hate that lap top and software so much haha. it's always needs a update that fails and take an hour to get working. so this is pretty good for me all around. it even needed to down fordeu data pack for this odd thing and it worked.

looked around.. got some info on keys, but no programming I saw. it can reset oil and few other things. but didn't seem anything about tranny fluid reset.

under that section it has stuff like oil life, brake breed, and stuff that doesn't work for our trucks, like brake pad sensor reset, steering wheel angle sensor cal, battery reset like the BMW need. it has after tb change idle relearn under there, but I don't try it.

I guess I need to pull the tech 2 out if you say it's going a tranny fluid reset somewhere.

the tech2 does have transmission fluid reset

 

[j91z28d1]

the tech2 does have transmission fluid reset

do you remember off the top of your head what it's under? I can probably find it. Just wondering

not from memory but it's probably under powertrain options

 

[Doubeleive]

found a tree to it for another model but will be the same just choose right car
Work around procedure with a TECH2 to reset the transmission oil life monitor.

1. On the TECH2, select Diagnostics.
2. 2009
3. Passenger Car
4. Cadillac
5. K
6. Powertrain
7. TCM
8. Module Setup
9. Reset Transmission Oil Life
10. Type 100%
11. Perform Reset

 

[j91z28d1]

thank you. I'd have never thought of that way

yeah, just took a look. no option for module setup under tcm. Just the trans daps relearn stuff it says to do after a rebuild. I'll leave that alone.

probably a hybrid thing. I looked everywhere else I could think of and nothing.


so that doesn't mean the dongle can't do it, just that I can't find it on this thing.

Spent my New Years Eve at the shop with my truck. Wanted to use the flat floor to get some vehicle height and camber measurements and rotate my tires and inspect things whilst doing so. Finally found that rattle that has been driving me nuts for months. At least I hope so anyway. I have been under the rear of this thing several times trying to find it. Don't know how I missed it. Hoping I have a nut that fit's it in my "Tahoe" fasteners bucket to fix it today.

"...driving me nuts..." I see what you did there...

 

[89Suburban]

Thinking about lowering the rear another inch or 2. And get rid of this stupid Chevy lean sh*t. So I took some measurements at: Front fenders, running boards, rear fenders, rear bumper lip.

Then camber measurements are whacked, no way this floor is level flat, probably sloped flat. I zero'd out the camber gauge on the r/r wheel and worked my way around. Usually I zero it out on each rear wheel and then measure the fronts.


And I measured rear axle to frame clearances at the bump stop mounts.

1/8"-1/4" isn't much of a "Chevy lean", If I'm reading your chicken scratch right, lol
